Because dynamic packaging propelled it there, dahrlings. How very clever of Sunquest to release themselves from the shackles of Canadian gateways and offer cheap packages from U.S. border towns.
Without all that aircraft baggage to worry about, I bet they could offer packages from anywhere - like Minsk or something. They need a mascot - Mr. Dynamo! Flying from whence no Canadian tour operator has flown before!
Unless you consider Sunwing's U.S. arm. (Where does that appendage not reach?) Their American tour operation isn't a border play, but it is a full fledged Canadian vacation invasion, eh? And then there's Goway's U.S. business which is growing faster than a speeding cricket ball.
The moral of this story is, Pumpkins, go south young man. (Come to think of it, older men are the ones who avoid anything south of the border, so to speak. God bless you, Frank.)
